The RTÉ Philharmonic Choir sings the traditional Irish carol Suantraí ár Slánaitheora.
The RTÉ Philharmonic Choir with soprano Ailish Tynan and reader Barry McGovern perform this beautiful lullaby in which the Virgin Mary glorifies the beauty of her new-born Son.
The performance, which was recorded individually on the singer's phones and then mixed together, features some special photographs in the video above.
